Principle

The keyboard pattern projector displays a virtual keyboard pattern on a flat surface, such as a desktop surface. When a user touches virtual keys using his/her fingers, the top of fingers will be illuminated by the lighting plane created by the linear laser. Since the infrared light is used, the user won’t notice his/her fingers are illuminated.


The infrared light camera captures the images of the illuminated fingers, and sends the images to the signal processing software. The position of the illuminated fingers is detected and localized by the software, and it will be transformed to the related key input events.
